Thisinvention relates to that type of hinge connectionsfor spectacle and like mountings in which the lens holding rings are ofthe fastening the rings on the vlenses and for pivotal attachment of the temple members,

and has for its object: l 1

To provide a structural formation and combinationof parts whereby a strong" and compact arrangement of parts `is attained with the covering and concealment at fro-nt of the scams or joints of the parts, all as will hereinafter more fully appear.

The present invention is shown in the drawing, ap lied to the outer portion of the split lens ho ding ring of a spectacle mounting, with such ring portion provided with the usual and approximately counterpart upper and lower lateral and rearwardly curved ears 2 and 3, with the connecting screw 4, by which the same are drawn together to effect a contraction of the split ring 1 and proper holding engagement with a lens, arranged separate from and in adjacent relation to the pintle or screw 5 by which pivotal connection is made between said ears and the temple member 6 of the spectacle mounting. In connection with the above described construction, the preferred form of the present iuvention comprises and involves a detail formation of the above mentioned parts as follows.

The portions of the ears 1 and 2, adjacentV to the connection to the split ring member l are of a. rectangular form in cross-section,

with the connecting screw 4 passingloosely Fig. 2.

',Ihei'emote oivouter portions ofthe ears 2 through the upper ear 2, with its head seated inria countoivsinkin saidear, and witl'rl its `screw threaded end screwing into a comple# j split type and have independent screws for nientary bore in the` lower ear 3, as showi'i'irr and 3 are of a` rounded shape, provided with align-ed central orifices for the neceptionof` the pivot screw 5 of the temple niember aforesaid, and concentric 4with saidorifliees`,

the upper partof the upper ear 2 is formed with a receiving offset or recess for t-lie upper pivot knuckle 7 of the temple 6, while the under part of the lower ear 3 is formed with s a similar receiving offset or recess for the lower pivot knuckle 8 of the temple 6.

ln the preferred construction shown each offset or recess just described is of a depth equal to one-half the height` of an ear 2 and 3, in which theparticular offset or recess is formed.

In order to fit and have proper operative connection 'with the ring ears 2 and 3 above described, the temple member 6 is formed with centrall oriliced upper and lower knuckles 7 andyS of a circular form as shown, with said knuckles arranged in separated relation corresponding with the distance between the heretofore described receiving olfsets or recesses in the ears 2 and 3, so as t0 tit snuglyV and turn in said recesses. With such construction the pivot screw 5 asses loosely through the lower knuckle 8, with its head seated in a counter-sink inY said knuckle, thence in a like loose manner through the orifices in the ears 2 and 3, with the upper screw` threaded end of the screw 5 screwing into a complementary orifice or `bore in the upper knuckle 8 of the temple 6.

vA material feature of the present improvements consists in forming the upper ear 2 aforesaid of a less width from front to rear, than the companion nlower ear 3, and providing said lower ear 3 with an upstanding flange 91the extent of the forward face and of a height equal to the height of the upper ear 2. This construction provides a` receiving cavity `for said upper ear to conceal from view the horizontal seamor joint between saidl upper and lower ears. Sucli construction imparts rigidity to the connections between the ears as well as to the connection of the temple, and thus admits of a compact formation of the present parts. Having thus fully described my invention,

lll)

what I claim and desire to secure by Letters Patent, is

' l. In a Spectacle mounting, the combination of a. split lens holding ring having lateral ears at its point of split, a connecting screwv passing through said ears adjacent to the point of attachment of the sume to the split ring, the outer portions of said ears having centrally orificed recesses of a circular form, a temple member having pivot knucklesjfitting said i'eeessesrand un individua-l screw connecting the temple member and lateral enrstogether, one of-said ears havinga, flange at its front side extending the transverse length of the same and of :L height equal to the height of the, other ear,

with such other ear of ay reducedv width to fit therocess; formed by said Bange. 2. In e spectaclel mounting the combi- 20 nationL of a, split lens holding ring having lateral ears at its point of split a connecting screw assng through said ears adjacent to the point of attachment of the same to the split ring, the outer portions of said ears havinff cular orm in the outer portion of the upper face of the upper ear, and in the outer portion ofthe under face of the lower ear, a, temple member having pivot knuckles fitting said recesses, and an individual screw conneeting the-temple member andwluterzil vears together, one of said ears having a flange at its front side extending thev transverse length of the same and ofa height equal to the height of the other ear,- with said other centrally` orificed recesses of a eiri' ear of :i reduced. width. to fit the recess Y formed by said flange.
